I have suffered from severe migraines since I was at least 5 years old my neurologist told me I shouldn't get headaches whilst pregnant and I've had about 5 bad migraines in the last 18 weeks. At first I didn't take anything when a headache came on which in turn lead to a migraine but my dr said it was ok to take one panadol and drink lots of water and if within an hour nothing happened take another so now when I get a headache probably about 4 to 5 times a month this is what I do and 9 times out of 10 it goes away.
